Slovenija: 'Spend, Spend'

Russia needs to get its act together

While our American friends show how it's really just child's play, Vova, with his persistent love of Rube Goldberg mechanics, makes himself look like a really bad Bond villain...

James Bond: "Do you expect me to talk?"
Bond villain: "Haha no Mr. Bond, I expect you suffer a suspicious, but recoverable, ailment in a public place, using an easily traceable substance, in the middle of the most tense geopolitical situation since the Cold War, weeks before my country hosts the FIFA World Cup."

FFmpeg: Colour animation from macroblock motion-vectors

The animation is created from styling the macroblock motion vectors, as displayed by FFmpeg, rather than by manipulating the actual video content. The blocks of colour are created by stacking 'dilation' filters on the motion-vector layer. Before being dilated, the colouring of the arrows is extracted from the original video by 'colorkey' overlay. Based on an earlier filtergraph experiments.¹

# Generate stylised animation from video macroblock motion vectors, 
# and present in a side-by-side comparison with original video.
